It may be phosphorus but it may be lockout from pH.
(Figure 12 shows Phosphorus (P) deficiency during vegatative growth. Many people mistaken this for a fungus, but look for the damage to occur near the end of leave, and leaves the color dull greyish with a very brittle texture)
I saw this pic the other day and your plant reminded me of it. I hope this helps man. Nice looking plant. Good luck.
She looks nice. Here is a thought. I top off my rez daily with water about 16 oz of distilled water. Your plant is alot bigger than mine. How much water does it take a day and how often do you top off? If you are only topping off once a day maybe try topping off a couple times a day or even 3 times if it drinks that much. Your rez must not hold much water with all them roots in there.ok flushed the res and gave them fresh water.
also clipped the bad leaves in the pics.
yea the Aerogarden res is a lil less than a gallon and I go through almost a gallon every day now topping off every 4-6 hrs w/ ph balanced filtered water (from fridge pur water filter) they def drink alot.She looks nice.

you have to get the WIDE RANGE ph test kit.I wish i knew what your PH was exactly cuz when i look at your pics and your test tube that dark orange/red color you are getting seems bothersome to me. Cuz when i test mine (and i have the same testing supplies cuz im cheap) I can just get really light yellow... no matter how much phdown i put in the test tube. =X anyways good luck man hope all turns out well

I did the same thing and just bought one only to find out it only goes as low as 6.0. meaning it will only show yellow. so be carful with the PH down.
red is 5.0 so....I try to get it yellow with a tint of red (slightly orange) hoping to be close to the 5.7-5.8 recommended PH level.
only problem was that the AG nutes made my PH go up and the Fox farm was makin it go down. so whrn i took the AG nutes out my PH was lower than usual and i didnt catch it.
next grow im getting a digital PH reader
